JAMES W. CARTER, OF ABILENE, TEXAS.

ELECTRIC-LIGHTHANGER.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application led. Octoberj, 1907. Serial No. 396,308.

To all whom *it may concern:

Be it known that I, J AMES W. CARTER, a citizen of the United States,residing at Abilene, in the county of Taylor' and State of Texas, haveinvented a new and useful Electric-Light Hanger, of which the followingis a specication.

This invention relates to electric light hangers of that general classshown and described in United States Letters Patent issued to me on the30th day of October, 1906 under N o. 834449.

The object of the invention is generally to improve and simplify theconstruction of the hanger and to reduce wear and friction on theelectric conductor incident to adjusting` the lamp by the employment ofa separate suspension cord.

A further object of the invention is to provide the movable sheave orpulley with a depending bulb or receptacle adapted to contain a quantityof shot or the like, said receptacle being detachable so that the samemay be readily disconnected from the pulley to permit the introductionor removal of a portion of the shot thereby to nicely balance the lamp.

A further object is to provide a ceiling bracket having a threadedsocket formed therein for engagement with the correspondingly threadedshank of a stationary pulley, there being a similar' shank formed on themovable pulley so that said pulleys may be reversed and used vinconnection with either a ceiling bracket or the shot containingreceptacle.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefliciency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

In the accompanying drawings forming a part of this specification:Figure 1 is a side elevation of an electric light hanger constructed inaccordance with my invention. Fig. 2 is a vertical sectional view of themovable weight supporting pulley.

is a bottom plan view of the same with the shot containing receptacleremoved. Fig. 4 is a perspective view of the clamp detached. Fig. 5 is aside elevation of one of the pulleys showing the face plate in openposition. Fig. 6 is a side elevation partly in section illustrating amodified form of the invention.

Similar numerals of reference indicate corresponding parts in all of theiigures of the drawings.

The improved hanger forming the subject matter of the present inventionis principally designed for attachment to a wall, ceiling or othersuitable support for holding an incandescent lamp in adjusted positionand by way of illustration is shown in connection with an incandescentlamp of the ordinary construction in which 5 designates the lamp, 6 theflexible conductor and 7 the ceiling block fastened in any suitablemanner to the support S, as shown.

The device includes a bracket 9 adapted to be fastened to the ceiling 8in spaced relation to the block or rosette 7, said bracket beingprovided with a socket 10, the interior walls of which are threaded forengagement with the correspondingly threaded shank 11 of a relativelystationary pulley 12.

Secured in any suitable manner to a ceiling block or rosette 18 is oneend of a cord or other :flexible medium 14 the opposite end of whichpasses over a relatively movable pulley 15 and thence over thestationary pulley 12 for attachment to the conductor G. The suspensioncord 14 is connected with the conductor 6 by means of a clamping devicepreferably formed in two sections 17 and 18 each provided with alinedgrooves or channels 19 adapted to register with each other when thesections are assembled to form longitudinal seats for the reception ofthe conductor and suspension cord, respectively, said sections beingclamped in engagement with each other and with the members 6 and 14 bymeans of a clamping screw 20.

The pulleys 12 and 15 each comprise a casing or housing having a rigidback plate 2l and a removable face plate 22, said back plate beingformed with a segmental section or guard 23 and an integral laterallyextend- Fig. 3 l ing stud 24. The face plate 22 of each pulley isdetachably secured to the stud 24 by means of a screw or similarfastening device 25, there being a locking lug or lip 26 extendinginwardly from the lower end of the face plate 22 and adapted to engage acorrespondingly shaped socket 27 formed in the seg- Vmental plate orguard 23 therebyto assist in preventing accidental displacement of saidface plate. rllhe stationary rear plate 21 of each pulley is alsoprovided with a laterally extending pin 28 on which is mounted forrotation a sheave of the ordinary construction.

Depending from the plate or guard 23 of the pulley 15 is a threadedshank 29 similar in construction to the shank 11 of the pulley 12 andadapted to engage the correspondingly threaded neck of a circular weightreceiving receptacle 30. The receptacle 30 is detachably secured to theshank 29 and isadapted to contain a quantity of shot, pebbles, sand orother material which acts as a counter balance for the lamp 5 so thatthe latter may be readily adjusted to any desired height with verylittle exertion on the part of the operator. The stud 24 of each pulleyis provided with a loop or eye 31, the eye of the pulley 15 beingconnected with the ceiling 8 by means of a cord, cable or other flexiblemedium 32.

1n order to attach or detach the pulleys 11 and 15 from the suspensioncord 14 it is merely necessary to loosen the screws 25 and then pressoutwardly on the face plates 22 until the lugs 26 are disengaged fromthe sockets 27, after which the plates are shifted laterally to theposition shown in Fig. 5 of the drawings and in which position the adjacent sheave may be readily removed from its journal so as to permit thecable 14 to be adjusted to said sheave. To close the plates a slightlateral movement is exerted on said plates until the lugs 26 enter thesockets 27 after which the screws 25 may be tightened thus securelyclamping the several parts together.

A stop lug 33 is preferably clamped on the suspension cord 14 to assistin limiting the downward movement of the weight 8O and also to preventthe free end of the cord from being drawn through the pulley 12 by theweight of the pulley 15 when the conductor 6 is detached from thesuspension cord.

1t will thus be seen that the entire weight of the lamp is supported bythe suspension cord 14; thus preventing undue wear and friction on theelectric conductor when adjusting the lamp. 1t will also be noted thatby forming the pulleys with correspondingly threaded shanks, saidpulleys may be either attached` to the wall or used for supporting theshot containing receptacle.

' The side walls of the plates 21 and 22 are preferablyV curved orrounded, as indicated at 34, so as to prevent cutting, abrading orotherwise injuring the suspension cord when the device is in operation.1

In Fig. 5 of the drawings there is illustrated a modified forrn of theinvention in which the conductor 6 together with the lamp isr supportedon the ceiling of a room while the hanger proper is arranged within anattic above the ceiling 8 so as to be hidden from View, one end of thecord or cable 14 being extended through an opening in Ythe ceiling forattachment to the conductor,

in the manner before described.

Attention is called to the fact that the several pulleys are similar inconstruction and of the same size thus requiring but a single mold orset of molds to cast the same.

1f desired, the suspension cord of the hanger shown in Figs. 1 and 2 ofthe drawing may be extended longitudinally beyond the adjacent clamp forattachment to the lamp instead of terminating at said clamp.

In some cases the stationary pulley may be formed with an ordinary woodscrew so that the same may be screwed into the ceiling or other supportwithout the employment of the ceiling bracket. Y

Having thus described the invention what is claimed is:
